FX630 Large-Diameter PE Pipe Welding Test｜Factory Operation Summary
Last week, a welding test was carried out in the factory workshop using the FX630 butt fusion welding machine on a large-diameter PE pipe. The test followed standard operating procedures and focused on evaluating performance on thick-wall pipe applications while documenting the complete workflow.
01｜Pipe Setup and Alignment
The PE pipe was positioned in the FX630 main frame, fitted with the appropriate clamp inserts, and adjusted to maintain proper center alignment.
Accurate alignment is essential for achieving consistent weld quality.
02｜Facing Preparation
The facer was lowered into position using the lifting device and engaged to prepare the pipe ends.
The facing process produced:
· Smooth, flat end surfaces
· Removal of the oxidized layer
· A clean, uniform interface for heating
Shavings were cleared promptly to maintain a clean working area.
03｜Heating at 220°C
Once the hydraulic unit indicated the heater had reached 220°C, the heating phase began.
Because of the pipe’s diameter and wall thickness, heating took approximately ten minutes to ensure adequate thermal penetration.
During this stage, attention was given to temperature stability and proper contact between the heating plate and pipe ends.
04｜Fusion
After heating, the heater was removed, and the pipe ends were joined under controlled hydraulic pressure.
The movement was steady, and the initial bead formed cleanly along the joint.
05｜Weld Inspection
After cooling, the weld showed:
· A symmetrical, well-shaped bead
· No noticeable misalignment
· A clean and stable joint appearance
The results reflect consistent performance of the FX630 in large-diameter, thick-wall PE pipe welding.
Conclusion
This test demonstrates the FX630’s welding process and weld quality under practical operating conditions, providing a useful reference for large-scale pipeline applications.
